Extract

Despite the potential importance of southern Iran, and the Persian Gulf area in particular, for discussions on the dispersal of early hominins from Africa into Eurasia during the late Pliocene and early Pleistocene (Bar-Yosef & Belfer-Cohen 2001; Rose 2010), this area has remained almost unexplored until recently. Historically, Palaeolithic survey and excavations in Iran have mainly concentrated in western regions, especially the Zagros Mountains. As a result of recent studies, however, evidence for Palaeolithic sites in the southern regions of Iran, from Fars province to Qeshm Island, has greatly increased (Dashtizade 2009, 2010). Even with this improvement, no sites of Lower Palaeolithic date have yet been reported from the southern coastal areas on one of the proposed early hominin routes into Eurasia. As a result, it has been suggested that the few Lower Palaeolithic sites reported from other parts of Iran, especially in the west (e.g. Biglari & Shidrang 2006), were not populated from the south.

Despite the potential importance of southern Iran, and the Persian Gulf area in particular, for discussions on the dispersal of early hominins from Africa into Eurasia during the late Pliocene and early Pleistocene (Bar-Yosef & Belfer-Cohen Reference Bar-Yosef and Belfer-Cohen2001; Rose Reference Rose2010), this area has remained almost unexplored until recently. Historically, Palaeolithic survey and excavations in Iran have mainly concentrated in western regions, especially the Zagros Mountains. As a result of recent studies, however, evidence for Palaeolithic sites in the southern regions of Iran, from Fars province to Qeshm Island, has greatly increased (Dashtizade Reference Dashtizade2009, Reference Dashtizade2010). Even with this improvement, no sites of Lower Palaeolithic date have yet been reported from the southern coastal areas on one of the proposed early hominin routes into Eurasia. As a result, it has been suggested that the few Lower Palaeolithic sites reported from other parts of Iran, especially in the west (e.g. Biglari & Shidrang Reference Biglari and Shidrang2006), were not populated from the south.

In order to show that this hypothesis is not correct and that the southern coastal area of Iran has the capability to provide evidence of Lower Palaeolithic groups, extensive survey was conducted on Qeshm Island, which was considered a location likely to produce evidence for early Palaeolithic activity. Reconnaissance was focused on the elevated areas of the island, with its caves and rockshelters. An assemblage of Palaeolithic artefacts was discovered at the Khorbas Cave and rockshelters on the present-day coastline of the island. In addition to Palaeolithic artefacts, the survey also recorded historic and late Islamic pottery at the site. In addition, a number of other sites, all of historic date, were identified on the island.

The Khorbas site is located 10km south-west of Qeshm City on the Persian Gulf coast (Figure 1). The site had been previously surveyed by both Iranian (Khosrowzadeh Reference Khosrowzadeh2005) and foreign scholars (Potts & Petrie Reference Potts and Petrie2004), but the oldest archaeological evidence reported to date reached back only to the Parthian era (Potts & Petrie Reference Potts and Petrie2004; Khosrowzadeh Reference Khosrowzadeh2005). The majority of finds belong to recent Islamic times, when the area seems to have served as a port. The site was resurveyed by a team directed by the present author, and although it had been badly damaged by recent activities, including road construction, an assemblage of Palaeolithic artefacts was identified. This included handaxes, a chopper, a hammerstone and a core; a number of flakes were also recovered and even though these cannot be attributed to the Palaeolithic on stylistic grounds, they were, however, recovered from the same concentration as the tools (Figures 2–6). Due to the absence of suitable raw material sources such as high-quality local cherts in the vicinity of the site, the artefacts are all of local limestone.

Another Palaeolithic site on Qeshm Island, at Bam-e Qeshm, was previously identified by survey and subsequently excavated by Iranian archaeologists, providing a Middle Palaeolithic date (Dashtizade Reference Dashtizade2010; Rahmati Reference Rahmati2016). The preliminary analysis of the artefacts from Khorbas suggests a Lower Palaeolithic date, which would make it the oldest Palaeolithic site yet reported from Qeshm Island.

Reconstructing the specific context and function of the Khorbas site is challenging. It may have been a coastal settlement, but the configuration of the Persian Gulf changed repeatedly during the Pleistocene. Global sea levels during the Last Glacial Maximum (70 000–17 000 BP) were up to 120m lower than today, and therefore the Persian Gulf was dry during the late Pleistocene. After 17 000 BP, global sea levels began to rise, reaching approximately modern levels by 7000 BP (Potts Reference Potts and Potter2009). As a result, without closer dating, it is currently impossible to propose any specific context or function for the site. As mentioned above, however, southern coastal Iran has been suggested as one of the routes of early hominin dispersal into western Asia. The discovery of a new Lower Palaeolithic site on Qeshm Island may lend support to this hypothesis. Further work to refine the date of the Khorbas site, and to identify other Lower Palaeolithic sites in this region, should therefore be a priority.
